The record time for the co-op game type "Hangman's N.O.O.S.E." was broken four times in one night.  How, you say?  well it turns out that there is no actual way to get this record.  A time glitch was discovered that allows the main objective of the game (to save petrovic) to be transported to the "safe point" without actually bringing him there. two men leaves to get a chopper and flies directly to the safe point without picking up petro. the one man who stays behind, shoots fifteen men and picks up petro. as soon as the other two in the chopper reaches the safe zone the player in the vehicle with petro leaves and petro is automaticly transported to the safe zone.  the leaderboard for this once great task is dead and this glitch is a disgrace to all pro-gamers in the world of GTA IV.  if you ever go for a leaderboard score do it right, boosting, glitching, and hacking is never the right way.
